Introduction

Various popular feature learning methods such as sparse coding, Robust PCA, CCA, and Group sparse coding have been explored in multi-view multi-modality gait recognition and intelligent visual surveillance system applications.

Gait recognition is a popular pattern recognition problem for which attracts a lot of researchers from different communities such as computer vision, machine learning, biomedical, forensic studying and robotics.This problem also has great potential in industries such as visual surveillance. Hence, The Intelligent Recognition & Digital Security Group, which was formed in 1998 by Prof. Tieniu Tan at NLPR (National Laboratory of Pattern Recognition), developed this CASIA dataset since Dec. 10, 2001. This CASIA Gait Recognition Dataset current contains 4 subset: Dataset A(standard dataset), Dataset B(multiview gait dataset) and Dataset C (infrared gait dataset), and Dataset D(gait and its corresponding footprint dataset). The contributions of the project are two folds. 1) We create a new database contains gait and foot pressure image(footprint), which would help further studies on gait. It becomes Gait CASIA Part D sub dataset. 2) We demonstrate how to address most important problem in gait recognition by employing some popular machine learning techniques such RobustPCA, Group Sparse Coding and etc.

  1. Sir can please send me the matlab code to extract gait energy from gait cycles (From silhouettes).
    Thank You

  2. Hi, Iftikhar, You can get Gait energy by doing these. 1) Compute the cumulative of the silhouttes in one gait cycle, 2) Divide this by the number of frames in one gait cycle. The results would be similar to what GEI we provided in this website. Let me know if you need more help in this. I will try to find that bit code for you and release it here. Cheers. Kyle

  3. I read a lot of interesting posts here. Probably you spend a lot of time writing, i know how to save you a lot of work, there is an online tool that creates high quality, google friendly posts in seconds, just search in google – laranitas free content source

  4. Hello Sir,
    Can you mail me a code.?
    Because I want to take trials on live video..
    This is just for learning about different pattern recognition methods..

  5. Please Admin,

    I urgently need the matlab code for generating the GEI from the silhouette.

    Thanks in advance

  6. Dear sir,
    I gone through the the gait recognition system you proposed. I found it very interesting and useful for my work. I want to begin in computer vision area by gait analysis. Could you please provide me matlab code which you have written?
    Thanks and regards,
    Om Prakash

  7. Sir,
    In your paper “A Cascade Fusion Scheme for Gait and Cumulative Foot Pressure Image Recognition”,how to determine the dimensions of pbHOGs? Do pbHOGs extracted from every frame have the same dimensions?Is the dimensions of concatenated pbHOG representation same with that of pbHOGs or (N*dimensions of pbHOGs) ?(N is the number of frames in one gait cycle)
